NE556 Datasheet (Philipss)

NE556, Dual timer

Both the 556 and 556-1 Dual Monolithic timing circuits are highly stable controllers capable of producing accurate time delays or oscillation.

The 556 and 556-1 are a dual 555.

Timing is provided by an external resistor and capacitor for each timing function.

The two timers operate independently of
